Stitch - we all knew this. The attraction is dismantled already.
Primeval Whirl - it makes sense to close it to save money, it isn't a crowd pleaser or even a good ride, and seems to be a maintenance nightmare. Hopefully, when things recover, this means Dino-Rama will finally get the axe.
Rivers of Light - I actually really enjoyed it in its original form. It was beautiful and the music was great, almost Reflections of Earth level IMO. It did suffer from pacing issues though and a definite lack of a "punch" or wow factor that nighttime spectaculars need. The entire run of this show's existence was problematic from beginning to end. It sucks that there's now a huge stadium carved into the place that kind of ruined the atmosphere around Everest a bit, but I have confidence that it will be used again... sometime...
